The chemistry of heterocyclic carbenes has experienced a rapid development over the last
years. In addition to the imidazolin‐2‐ylidenes, a large number of cyclic diaminocarbenes …

Carbenes, thought of only as transient species for a long time, have become ubiquitous in
organometallic chemistry. Their interaction with a metal center, which allows for their …

The use of N-heterocyclic carbenes as ligands for transition metals has increased
dramatically in the last few years, spurred on by their remarkable successes in the areas of …

We provide an overview on the state‐of‐the‐art in transition‐metal complexes formed with
water‐soluble NHC ligands. Paths to introducing water solubility by ligand design are …

Abstract Die Chemie der heterocyclischen Carbene hat sich in den letzten Jahren stürmisch
entwickelt. Nach den Imidazolin‐2‐ylidenen wurden weitere cyclische Diaminocarbene mit …

Since the isolation and crystallographic characterization of the first stable N-heterocyclic
carbene in early 1991, 1 nucleophilic diaminocarbenes (also known as “Arduengotype” …

Stable mono‐and dicarbene adducts of late transition metals are readily accessible either by
reaction of imidazolium salts with metal complexes bearing basic ligands, or by the cleavage …

Recently, transition-metal complexes containing nucleophilic N-heterocyclic carbenes
(NHCs) have been receiving increased attention in the literature, largely due to their …

Evidence for the Wanzlick equilibrium between carbene 1 and dibenzotetraazafulvalene (1)
2 at ambient temperature has been found (see scheme). Enetetramines of type (1) 2 can …

The coordination chemistry of stable or in situ accessible carbenes is still rapidly developing.
Owing to their strong basicity, they may act both as ligands in coordination compounds and …
